Feeding mechanism for work pieces



W. N. STEVENSON. FEEDING MECHANISM FOR WORK PIECES. APPLICATION FILED JAN. 3, I921.

Patented Aug. 8, W22.

@Ww I lies a resilient presser foot K that is adapt ed to overlie a work-piece, such, for instance, as shown at X, so that when the slide C moves forward and the roller K runs down the inclined forward end of the cam L, the presser-foot K will displace the work-piece X from the path of introduction and seat it in position to receive the plunger. This dispiece a part of the distance toward its seatso that the plunger will force it completely to its seat in acting upon it. The slide C will preferably carry adjacent the workpiece X a pusher M to engage the work-piece in the direction of introduction to the press, and this pusher may have any approved form adapting it to properly control the Work-piece in the plane of introduction.

I claim:

1. A feeding means for pressescomprisng an introducing member adapted to travel 111 a path to introduce a work-piece to the press, and a displacing member mounted upon and partaking of the introducing movements of the introducing member, and having an independent movement thereon to move the work-piece from the path of -introduction when it arrives in position to re celve the action of the press.

2. A feeding means for presses comprisng an lntroducing member adapted to travel in a path to introduce 'a-work-piece to the press, and a displacing member mounted upon and partaking of the introducing movements of the introducing member and having an independent movement thereon to move the work-piece from the path of introductlon when it arrives in position to recelve the action of the press; said displacing member receiving its displacing move ments from the movement of the introducing member.

3. A feeding means for presses comprising a sliding carriage adapted to introduce a work-piece to the press, a displacing member pivotally mounted on said carriage 1n position to overlie a workpiece being fed by the carriage, and means for imparting movement to said displacing member transversely to the path .of introduction. 7

4. A feeding means for presses comprising a sliding carriage adapted. to introduce a workpiece to the press, a displacing member pivotally mounted on said carriage in position to overlie a work-piece being'fedi by the carriage, and means for imparting movement to said displacing member comprising a spring for swinging said member in one direction and a cam for moving it in the other direction.

5. A feeding means for presses comprising av sliding carriage adapted to introduce a work-piece to the press, a displacing member pivotally mounted on said carriage-in position to overlie a work-piece being fed by the carriage, and means for imparting movement to said displacing member transversely to the path of introduction; said displacing member having a resilient presser foot through which it acts-upon the work-piece.

6. Means for feeding work-pieces to a press comprising a carriage adapted to receive a work-piece and present it to the press, a displacing member movably mounted on sald carriage, means moving said displaclng member on said carriage, transversely to the path of the carriage before the workpiece reaches the press, and a resilient presser foot through which the displacing member acts upon the workpiece. y
